No Automatic Home Story Settings
There is no Automatic Home Story setting in ARCHICAD 19. Elements from older projects (older than AC13) whose Home Story was set to Automatic will now be assigned Home Stories that correspond to the story they were placed on.
In ARCHICAD 19, during editing operations that affect the elements’ elevation (e.g. elevate, multiply with vertical displacement), you have the option to automatically re-assign those elements’ home stories accordingly.
